The machine that Casey Stoner has been testing – the Honda RCV1000R prototype – was unveiled Thursday at Valenica ahead of the 2013 MotoGP season finale.

The RCV1000R prototype will be used in the 2014 MotoGP “Open” Class, which is limited to a 24-liter fuel tank and 12 engines per season. This is the bike that the American Nicky Hayden, who leaves Ducati following this weekend’s round, will pilot for the Aspar team.

The RCV1000R, which uses Magneti Marelli hardware and software, is based on the current RC213V prototype used by the Repsol Honda team of Marc Marquez and Dani Pedrosa. The RCV1000R features a 90-degree V4 with spring valves that produces 235 horsepower at 16,000 rpm, a traditional gear box, Ohlins suspension and Nissin brakes.

The bike was presented to the media by Honda Racing Corporation Vice President Shuhei Nakamoto and Project leader, Tomonori Sato.

As stated, Hayden will pilot the RCV1000R for Aspar in 2014 MotoGP. As for his teammate, the rider has yet to be determined. The new Honda will also be used by Honda Gresini’s Scott Redding, and Cardion AB Racing’s Karel Abraham.

Two RCV1000Rs will be available Monday for the traditional, post-season test at Valencia.
